ABSTRACT

A self-guiding shopping cart collection, storage, and retrieval system is provided which is integrated into the parking lot construction. A collection channel is adjacent and parallel to a row of parking spaces which is formed as an inset trough configured to allow rolling translation of a shopping cart to a collection end. The collection channel has a generally planar floor and at least one inclined side bank with the floor being downwardly linearly inclined toward the collection end. Lateral feed channels intersect with the collection channel which are configured to allow rolling translation of a shopping cart from the parking lot into the collection channel. Thus, shopping carts from the parking lot are introduced into the lateral feed channels at the parking lot level and guided therethrough into the collection channel.

RELATED APPLICATIONS

This application is a division of U.S. patent application Ser. No.10/771,858 filed Feb. 3, 2004 now U.S. Pat. No. 6,910,828.

FIELD OF THE INVENTION

This invention is related generally to the field of parking lot designretail establishments, and more particularly to a novel system for thecollection, storage and retrieval of shopping carts in a parking lot.

BACKGROUND OF THE INVENTION

It is common practice in the art of merchandising for merchants toprovide parking lots in which their patrons can conveniently park theirautomobiles and to provide wheeled, wire-basket type push carts,commonly referred to as shopping carts. Customers can deposit theirpurchases in these shopping carts while in the store and then thepurchases can be transported, from the store, into the parking lot andto the customers' automobiles, for final transfer into theirautomobiles.

Large shopping centers which provide shopping carts for customer use canhave parking lots which cover many acres of land. In such situations,customers typically move carts from the store in which they have shoppedto their automobiles in the parking lot, and after they have transferredtheir purchased goods into their automobiles they generally simply leavethe cart abandoned in the parking lot. The abandoned shopping carts inthe parking lot are a nuisance, as they require the merchants to hirepersonnel to move about the parking lots, collect the carts and returnthem to the store for further use. These abandoned shopping carts alsocreate serious traffic hazards in the parking lots, cause a disturbancein movement of vehicles throughout the lot, and are frequently damagedby customers' automobiles, and in turn cause damage to the automobiles.Moreover, such abandoned carts are subject to theft.

It has been clearly established that in places where customers have beenencouraged to return carts to stores from adjacent parking facilities,and in those places where special facilities have been provided inparking areas to accommodate emptied carts, damage, theft and all otherinconveniences normally associated with the provision and use of suchcarts has been materially and noticeably reduced.

It has also been determined that if customers are encouraged to deposittheir empty carts in specially provided receivers located in parkinglots great economic savings and more effective and efficient use ofcarts can be achieved.

Systems have been proposed for encouraging the users themselves to bringback to a storage station. One example is a system in which a voucher isissued to the customer attesting the return of the cart which includes acoupon or benefit of some sort. Various other methods have been proposedto alleviate the shopping cart abandonment problem, but none have beensuccessfully employed. Accordingly, the only common method in use forprotection from random storage of shopping carts is providing personnelfor the continuous manual recovery of the carts from the lots.

A cart storage device which carts can be directed or stored is disclosedin U.S. Pat. No. 4,236,697, invented by Savino. This patent discloses adevice, installed in parking lots or the like, consisting of upstandingrail guards within which carts can be directed or stored for recoverywhile being protected from damage by vehicles using the parking lot.

An apparatus for encouraging the restitution of shopping carts such asin a reception area otherwise controlled by wickets is disclosed in U.S.Pat. No. 4,428,893 invented by Gillet. This patent discloses anapparatus having vertically hinged doors and dispenses a ticket or tokenwhen the proper cart is moved therethrough. This apparatus alsoidentifies unacceptable shopping carts, which are dissimilar to thosefor which the apparatus is designed.

Mueller teaches a cart conveyer and dispensing apparatus in U.S. Pat.No. 4,518,072. This invention is directed to an enclosed conveyor forpropelling a shopping cart therethrough. Shopping carts are propelled byengagement of their wheels by a continuous member that carries a crossbump or upwardly extending protrusion.

Thus, what is needed is a shopping cart retrieval system which, withoutinterfering with traffic flow, will facilitate retrieval of shoppingcarts from a parking area or the like, store carts, and can dispensethem when desired.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

Although the invention will be described in terms of a specificembodiment, it will be readily apparent to those skilled in this artthat various modifications, rearrangements, and substitutions can bemade without departing from the spirit of the invention. The scope ofthe invention is defined by the claims appended hereto.

FIG. 1 illustrates a perspective view of a self-guiding shopping cartcollection, storage, and retrieval system according to a preferredembodiment of the invention. The system of the invention is implementedas a structure integrated into a parking lot construction, particularlya retail establishment parking lot where shopping carts are used. Theoverall arrangement can best be seen in the top plan view shown in FIG.2. The parking lot, generally designated as 5, includes the usual arrayof demarcated parking spaces. The system includes a plurality of parkingspaces 11 arranged as a row 17 which each include left and rightdemarcation lines 12,13 and a tire stop 14. The parking spaces 11 arespaced to define a plurality of aisle ways 16 therebetween. The aisleways 16 are preferably bordered by the demarcation lines 12 and 13 ofthe adjoining parking spaces 11, and are sized to allow a shopping cartof average dimensions to pass therethrough without contact to vehiclesparked in the parking spaces 11.

The system includes a collection channel 20 which is proximate to thetire stops 14. The collection channel 20 is adjacent and parallel atleast one the rows 17 of parking spaces 11. The collection channel 20 isformed as an inset trough in the parking lot 5 and is configured toallow the rolling translation of a shopping cart along the length of therow 17 to a collection end 22. FIG. 1 illustrates shopping carts 6 shownin phantom inside the collection channel 20. As can be seen in thecross-sectional views shown in FIGS. 3 and 5, the collection channel 20has a generally planar floor 23 and at least one inclined side bank 24with the floor 23 being downwardly linearly inclined toward thecollection end 22. In the practice of the invention, the collectionchannel 20 is constructed of a rigid, weatherproof material which is setinto a substrate. The collection channel 20 can be constructed from thesame material as the parking lot surface, such as concrete or asphalt.Any other material of a suitable hardness and durability can also beused, such as plastic, metal, fiberglass, etc.

A plurality of downwardly inclined lateral feed channels 30 intersectwith the collection channel 20. The lateral feed channels 30 aredimensioned to receive forwardly rolling shopping carts and have anupper end 36 contiguous to the parking lot 5 and a lower end 38contiguous to the floor 23 of the collection channel 20. The lateralfeed channels 30 are aligned with the aisle ways 16 so that a shoppingcart can be pushed through the aisle ways 16 between parked vehicles anddirectly into the lateral feed channels 30. The lateral feed channels 30are configured to allow rolling translation of a shopping cart from theparking lot 5 into the collection channel 20. As shown in FIG. 4, eachof the lateral feed channels 30 have opposing side banks 32, 33 whichserve to maintain a shopping cart therein. Shopping carts from theparking lot can thus be introduced into the lateral feed channels 30 atthe parking lot level and are then guided therethrough by the opposingside banks 32, 33 into the collection channel 20. The lateral feedchannels 30 are preferably angled toward the collection end 22 so thatshopping carts in the lateral feed channels 30 are directed into thecollection channel 20 in a smooth uninterrupted fashion. The downwardlysloped floor 23 of the collection channel 20 then causes the shoppingcarts to roll toward the collection end 22. The collection channel 20can include side banks 27, 28 located between the aisle ways 16 to helpmaintain the alignment of the carts in the collection channel 20. Thecollection end 22 of the collection channel 20 includes an oppositelysloping ramp 41 which extends from the floor 23 to the level of theparking lot. The ramp 41 serves to halt the downward rolling of theshopping carts and also the shopping carts to be pushed up the ramp 41to the parking lot level so they can be retrieved.

The system of the invention in the foregoing description is depicted interms of a single row 17 which is adjacent a collection channel 20.However, as seen in FIGS. 1 and 2, the system of the invention can beimplement using dual rows of parking spaces in a head to headarrangement which share the central collection channel 20. In thisarrangement, the lateral feed channels 30 of the respective sides can bestaggered to prevent collisions of the shopping carts within thechannels.

The above-described configuration can be constructed using any suitablemethods and materials to provide the collection channel 20, lateral feedchannels 30 and other inventive features described herein which arenecessary to practice the invention. In an alternative embodimentdepicted in FIG. 6, the system can be constructed using prefabricatedcomponents. In this embodiment, the collection channel 20 is constructedfirst to provide a base structure. The collection channel 20 isinitially in the form of a generally semi-trapezoidal trough with aplanar floor and opposing divergently inclined side banks (FIG. 5). Thelateral feed channels 30 can be defined by providing a plurality ofbarrier units 50 having a quadrilateral configuration which are flushlyadjoined to the opposing side banks of the collection channel 20. Thebarrier units 50 are aligned with each of the parking spaces 11 so thatthe lateral feed channels 30 thus defined are in alignment with theaisle ways 16. Each of the barrier units 50 includes a front curbportion 52 adjacent to the floor of the collection channel and opposingside curb portions 54, 55. The opposing side curb portions 54, 55 areapproximately aligned with the demarcation lines 12, 13 of the parkingspaces 11. In the preferred embodiment, the perimeters of the barrierunits 50 are configured as parallelograms to provide the angled lateralfeed channels 30.

The barrier units 50 can be formed from any suitable material, includingconcrete, rubber, plastic, recycled materials, wood, fiberglass, metal,etc. The barrier units 50 of the invention can be constructed in anynumber of configurations as may be desired dependent on the materialbeing used. For example, the barrier units 50 can either be solidthroughout or can have an open interior. The units 50 can be constructedto provide a central planar surface suitable for displaying indicia,such as retail logos or other advertising. Indicia can also bepermanently incorporated into the surface in high or low relief.

It is to be understood that while a certain form of the invention isillustrated, it is not to be limited to the specific form or arrangementof parts herein described and shown. It will be apparent to thoseskilled in the art that various changes may be made without departingfrom the scope of the invention and the invention is not to beconsidered limited to what is shown and described in the specificationand drawings.
